What Mother Nature gave New Zealand merino sheep to wear outside is now available to you with the Icebreaker Men's Sierra Full Zip Shirt. This medium weight fleece top uses the natural insulating and moisture-regulating abilities of merino wool to keep you warm and dry. Made from Realfleece 260, this wool top has a smooth jersey exterior and a terry-knit, brushed interior to create air pockets that will conserve body heat. It is permeable to the outside air making it perfect for aerobic activities in cooler weather like a November hike or a weekend ski tour in April. Pull it on over your long johns for extra warmth in the wilderness or wear it over your workout clothes on your way home after a trail run. A full front zipper makes for easy on and off and gives you ventilation options while articulated raglan sleeves offer a wide range of motion. This long sleeve top has 2 zippered hand pockets and a zippered stash pocket on the sleeve. Styled like a modern cardigan sweater with an athletic fit, the Icebreaker Sierra Full Zip Shirt for men will look just as good in town paired with jeans as it does on the trail.
